When to go

Best time to visit Gansbaai

Gansbaai sits in a Mediterraneanclimate part of the Western Cape: drier, windier summers and cooler, stormier winters.

Best overall window

Strong overall mix: peak whale activity, mild days, and workable sea windows between weather systems.

Outside that window

More cold fronts and swell. Great whale buildup (Aug) but more cancellations on small boats.

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.

The overall row stays visible so you can compare it against the currently selected scope.
